Morot-Sir's essay gives an account of the relationship between Les Mots and the Critique de la raison dialectique with an unusual perspective that is both philosophical and linguistic. The article explores the deeprooted epistemological interdependence of auto-biography on the one hand and socio-historical analysis on the other, as two poles of the subject-object dialectic. In this perspective both texts are doomed to fail, as incomplete independent entities, but together make up the totality of the universal-singular which constitutes the necessary but unachievable human goal.
